RESUMO
Objective To evaluate the treatment effect of combination of dexmedetomidine and droperidol on emergence agitation during general anesthesia recovery period in the elderly undergoing thoracotomy. Methods Sixty patients with severe emergence agitation during general anesthesia recovery period undergoing thoracotomy for esophageal cancer or pulmonary lobectomy, aged 66-75 years, falling into ASA physical status Ⅱ or Ⅲ, were divided into three groups, 20 patients in each according to table of random number: group droperidol (group F) and group dexmedetomidine (group D) and group dexmedetomidine combining droperidol (group DF). In group F, 0.06 mg/kg droperidol was administrated via central vein. In group D, 1 μg/kg dexmedetomidine was pumped via central vein in 10 min, followed by continuous infusion of dexmedetomidine in 0.2 μg·kg-1·h-1 for 1 h. While in group DF, 0.03 mg/kg droperidol was administrated via central vein and 0.5 μg/kg dexmedetomidine was pumped via central vein in 10 min, then followed by continuous infusion of dexmedetomidine in 0.2 μg·kg-1·h-1 for 1 h. The agitation scores and the Ramsay scores were collected after the beginning of anti-agitation. Arterial blood partial pressure of carbon dioxide was tested. Postoperative complications including nausea and vomiting were recorded. Results Compared with group D, the agitation scores at 5, 10, 15 and 20 min in group DF were lower (P < 0.05). Comparing with group F, the agitation scores at 60, 90 and 120 min in group DF were lower (P < 0.05). The incidence of over-sedation in group DF and in group D was less than that in group F (P < 0.05). PaCO2 was unaltered in all the groups after treatment. The incidence of nausea, vomiting, bradycardia, hypertension, hypotension and respiration depression and long QT interval between the groups were comparable. Conclusion Combination of dexmedetomidine and droperidol is effective and safe in the treatment of agitation during sevoflurane general anesthesia recovery period in the elderly undergoing thoracotomy.
RESUMO
OBJECTIVE: To investigate the curative effect of penile elongation with four differentoperative approaches. METHODS: Through four different operative approaches (the coronary sulcus ringincision, Y or Z shaped incision or Z shaped incision combined with coronary sulcus ring incision), thepenile skin and fascia were degloved until the penile root. Then the superficial and deep dorsal penilesuspensory ligament were cut off. After electric coagulation of the residue ends, the two-side tissue at thefront of the pubic symphysis was sutured. Then the penile skin and fascia were repositioned and the incisionat the inner and outer plate was closed. RESULTS: The increased penile static length was (2.9 ± 0.2) cmwith abdominal wall Y incision (12 cases); (3.1 ± 0.3) cm with transabdominal modified Z incision (260 cases); (3.9 ± 0.7) cm with coronary sulcus ring incision (363 cases); (3.4 ± 0.8) cm with combined incision (39 cases). The lengthening effect was significantly different between the coronary ring incision and abdominal wall Y/Z incision (P < 0.05). The postoperative follow-up period was 6 months to 5.5 years without serious complications. Only 3 cases of subcutaneous hematoma occurred with treatment of debridement and drainage. 4 cases with ischemic necrosis at distal penile skin, were treated with debridement, dressing and physiotherapy, leaving no scar. CONCLUSIONS: Penile lengthening surgery are safe and effective through different approaches. The coronal ring incision has the best therapeutic effect.

Objective To evaluate the safety and clinical efficacy of retroperitoneal laparoscopic partial nephrectomy (LPN) in patients with incidental renal cell carcinoma.Methods Twenty-six patients with T1 incidental renal cell carcinoma treated with retroperitoneal LPN from Dec.2011 to Oct.2013 were analyzed retrospectively.The operation time,warm ischemia time,intraoperative blood loss,complications and prognosis of perioperative periods were collected.Results All 26 cases were operated successfully without conversion to open or other surgery.The operation period was 90-190 minutes.Blockage of renal artery was applied in all 26 cases,and the warm ischemia time was 15-30 minutes.The intraoperative blood loss was 100-360 ml.The drainage was removed 3-7 days postoperatively,and the hospitalization period was 7-12 days.All cases were clear cell renal cell carcinoma by pathological examinations,and showed negative surgical margins.No complications such as postoperative bleeding,inflammation and leakage of urine were occurred.All cases had normal renal function during the follow-up of 3-25 months without local recurrence or distant metastasis.Conclusion Retroperitoneal LPN for the treatment of T1 incidental renal cell carcinoma is worthy of application with the advantages of safety,minimal invasiveness,fewer complications,quick recovery and good nephron-sparing functional recovery.
RESUMO
OBJECTIVE: To evaluate the safety and efficacy of percutaneous nephrolithotomy (PCNL) solely guided by ultrasonography (US). PATIENTS AND METHODS: From May 2007 to July 2012, 705 24-F-tract PCNL procedures were performed (679 patients, of whom 26 had bilateral stones). Calyceal puncture and dilatation were performed under US guidance in all cases. The procedure was evaluated for access success, length of postoperative hospital stay, complications (modified Clavien system), stone clearance and the need for auxiliary treatments. RESULTS: The mean (sd) operating time was 66 (25) min, with a mean (sd) postoperative hospital stay of 3.98 (1.34) days. The patients experienced a mean (sd) haemoglobin level decrease of 2.24 (2.02) g/day and the overall stone-free rate at 4 weeks after surgery was 92.6% in patients with a single calculus and 82.9% in patients with staghorn or multiple calculi. Auxiliary treatments, including shockwave lithotripsy in 52 patients, re-PCNL in 41 patients and ureteroscopy in 18 patients, were performed 1 week after the primary procedure in 111 (15.7%) cases for residual stones >4 mm in size. The sensitivities of intra-operative US-guidance and flexible nephroscopy for detecting significant residual stones and clinically insignificant residual fragments were 95.3 and 89.1%, respectively. There were 94 grade 1 (13.3%), 17 grade 2 (2.4%), and two grade 3 (0.3%) complications, but there were no grade 4 or 5 complications. CONCLUSION: Total US-guided PCNL is safe and convenient, and may be performed without any major complications and with the advantage of preventing radiation hazards and damage to adjacent organs.

Objective To investigate the effect of preoperative pravastatin preconditioning on myocardial ischemia-repedusion(I/R)injury in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Sixty ASA Ⅱ orⅢpatients of both sexes aged 18-64 yr undergoing cardiac valve replacement under CPB were randomly divided into 4 groups(n=15 each):control group(group C)and 3 pravastatin groups receiving oral pravastatin 10,20 and 40 mg respectively every night for 7 days before operation(group P1-3).The number of patients receiving dopamine(≥5 μg·kg-1·min-1)and adrenaline was recorded from the termination of CPB to the end of operation,from the end of operation to 12 h after operation,during 12-24 h after operation and during 24-48 h after operation.Venous blood samples were taken from central venous line for measurement of plasme cTnI and CK-MB concentrations at 7 days before operation,before induction of anesthesia,at opening of the aorta and at 2,24 and 48 h after opening of aorta.Results The number of patients receiving dopamine and adrenaline was significantly less in group P3 than in group C(P<0.05).Plasma CK-MB and cTnI concentrations were significantly lower in group P3 than in group C(P<0.05).Conclusion Preconditioning with oral pravastatin(40mg/d for 7 consecutive days)can protect myocardium against I/R injury in patients undergoing cardiac valve replacement with CPB.
RESUMO
Objective To summarize the diagnosis,treatment and prevention of dysuria within 6 months after the suprapubic transvesical prostatectomy. Methods Twenty-four cases were retrospectively reviewed,including the data on the diagnosis, treatment and prognosis. Results Twenty-one of the 24 cases had received surgery. There were 9 cases with bladder neck stricture,9 cases with posterior urethra stricture and 3 cases with of remnant glands. Nine cases received transurethral bladder neck incision, 9 received open surgery ( bladder neck,posterior urethral incision) and 3 received transurethral resection of the prostate (TURP) plus bladder neck incision. The other 3 diagnosed as detrusor weakness were conservatively treated by indwelling catheter and they were improved one months later. None of these patients was readmitted into hospital for dysuria within 6 months after treatment. Conclusion The recurrence of dysuria post prostatectomy mostly ( 75% ) occurred within 6 months after surgery. A majority of these patients need a second surgery. To avoid a second surgery for postoperative dysuria, much attention should be paid to the operating technique and postoperative management.
RESUMO
ObjectiveTo investigate the expression of Snail in bladder urothelial carcinoma and evaluate its relationship with E-cadherin and a subset of T cell groups.MethodsImmunohistochemical method was used to detect the expression of Snail and E-cadherin proteins in tissue from 156 cases of bladder urothelial carcinoma and 80 cases of the para-cancerous mucosa. The proteins expression status was analyzed with clinico-pathological data. Meanwhile, correlations with Snail and CD4+, CD8+, CD4+/CD8+ were analyzed.ResultsThe positive rate of Snail in bladder urothelial carcinoma was 65.4% , which was significantly higher than that in para-cancerous mucosa (48.8%). The expression of Snail was significantly correlated with the clinical stage, pathological grade, tumor quantity, distant metastasis and tumor recurrence.There was negative correlation between the expression of Snail and E-cadherin in bladder urothelial carcinoma. Positive expression of Snail had a negative correlation with the number of CD4+ and CD4+/CD8+ , whereas it had no significant correlation with the number of CD8+.ConclusionsBy inhibition of the E-cadherin expression and inducing local immunosuppression, Snail might play an important role in the process of the invasion and metastasis of bladder urothelial carcinoma.
